FRANZ JAGER, OF SUI-IL, GERMANY.

HINGE FOR TILTING-BARREL GUNS.

T 0 all whom it may concern:

Be it known that I, FRANZ J Kenn, a subject of the Emperor of Germany,and resident at Suhl, Thiiringen, Germany, have invented certain new anduseful Improvements in Hing-es for Tilting-Barrel Guns.

In looking devices for tilting barrels in which the box of the lockingdevice is provided with one or more grooves intended to guide the barrelhooks the shaft of the hinge is generally mounted in the device freelyas a pin or a screw. This arrangement shows the drawback that thebearing surface of the hinge shaft is relatively small as the shaftcannot be too thick, in order to not weaken too much the box of thelooking device. Besides the side walls of the groove must be mutuallypropped with a View of preventing them bending,-which circumstancerenders the manufacture most difficult. The present invention remediesthese drawbacks by making the hinge shaft of a screw on which a ring isslid which not only increasesin a corresponding proportion thecircumference of the hinge shaft, but at the same time serves to propthe lateral walls on the inside, While the head of the screw supportsthem on the outside.

In the accompanying drawing, given by way of example, is shown one formof embodiment of the invention applied to a looking device for tiltingbarrels comprising two lateral barrel hooks.

Figure 1 shows the box of the locking device in combination with thebarrel, Fig. 2 is a top plan view of the box of the locking device,while Fig. 3 shows the hinge shaft.

The box 1 of the locking device is provided with two lateral grooves 2 2in which the barrel hooks 3 are guided.

Engaged in the hinge 4 of the box of the locking device is the hingeshaft 5, on which the ring 6 is slid, which engages a correspondinglylarge recess provided in the Specification of Letters Patent.

barrel hook 3. The hinge shaft 5 is formed of a screw by means of whichthe lateral cheek 8 of the locking box, which otherwise projects freely,is tightly pulled on the interposed ring 6. This ring 6 and the head ofthe screw 5 prop the relatively weak lateral wall 8 and prevent it frombeing bent toward the inside and toward the outside. The rings may alsobe easily replaced by other ones which are a trifle thicker, when thehinge has become loose owing to the wear and tear. The ring may besecured on the hinge shaft by means of a countersunk set screw 9 or thelike, so as to be prevented from rotating. It may also be provided withan extension in order to limit the motion of the hinge.

I claim:

1. In a fire arm, the combination with a barrel structure provided witha plurality of bearing hooks, of a breech-frame provided with slots forthe reception of the said bearing hooks, a bushing for each of saidbearing hooks interposed between the lateral walls of said slots, and ascrew for each bushing, passing therethrough and having a binding actionbetween the walls and bush- FRANZ JAGER.
